Dramatic changes in the attitudes toward human nutrition have taken place dur• ing the past decade. Food-related and medical professionals as well as consumers are now, more than ever before, aware of and concerned about diet, nutrition, and the beneficial and deleterious effects of food processing upon nutrients. The old saying "We are what we eat" is still relevant. Nutritious food will contribute greatly to consumers' good health and ultimately reduce medical bills. Food processing is essential to maintaining our food reserves from one harvest to another, thus letting us serve our daily meals regularly. If food processing is defined as including all treatments of foodstuffs from harvest to consumption, then more than 95% of our food may be considered as processed. In most cases, food processing and storage cause some reduction in the nutritional value of foods. Advances in food science and have resulted in an increase in nu• trient retention after processing. In addition, today's consumer better understands how to avoid excessive nutrient losses during food preparation. The information presented in this completely revised reference and textbook will help the reader to understand better the relationship between food processing and nutrient retention. The authors' scholarly contributions are greatly appreciated. With the publication of the first edition of Nutritional Evaluation of Food Processing, Dr. Harris was the very first scientist in the world who compiled, systematized, and presented data on the effects of food processing on the nutrient composition of foods. I must state with deep sorrow that Dr. Harris passed away while the third edition was in preparation. I remember the first time I met Dr. Harris. He invited me to collaborate on the second edition. At first I was reluctant to accept his invitation and suggested several names of renowned nutritionists, who, in my opinion, were much more qualified for the task. Dr. Harris replied, "I am a nutritionist! I need a food technologist, who already has experience in publishing books, to help me!" I accepted his invitation, and from that moment on, a close collaboration and friend• ship developed between us. The second edition and the present edition, the third, are the two last additions to Dr. Harris's nearly 300 scientific publications. Perhaps one of the saddest moments in Dr. Harris's life occurred when he had to tell me that his illness prevented him from further helping me with this edition. At this tragic point, his battle with an incurable disease had already progressed too far. I will always remember, with great gratitude, my association with Dr. Harris who was a competent and distinguished scientist, a compassionate and generous man, and a committed and true friend!
